Description
Calculate care-work diary minutes as a share of observed minutes.
Aging research distinguishes participant and informant identities, calendar-month coordinates, time-use exposure and event/censoring status. Proxy responses and missing codes carry different meanings from direct observations. Local record summaries do not establish lifespan, legal status, accessibility or appropriate care.
Calculate care-work diary minutes as a share of observed minutes.
When to use this tool
Use Care Work Diary Minute Share when checking the stated aging-study record, timing, censoring or support convention.
How to use the tool and how it works
- Enter careMinutes, observedMinutes, excludedMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read eligibleMinutes, careFraction. Use the output convention below.
Require observedMinutes>excludedMinutes>=0 and careMinutes within the retained interval. Return eligibleMinutes=observed-excluded and careMinutes/eligible.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| careMinutes | Care time already on the retained observed-minus-excluded reporting basis. | Required. Finite number; minimum 0. |
| observedMinutes | Observed Minutes | Required. Finite number. |
| excludedMinutes | Excluded Minutes | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| eligibleMinutes | Eligible Minutes | Required. Finite number. |
| careFraction | Care Fraction | Required. Finite number. |

}Limitations and assumptions
- Care minutes must already exclude discarded time; the share does not measure burden, quality or a suitable level of care.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified original records and suitable complete research methods; involve qualified health, accessibility or legal professionals for actual care or rights decisions.
